9.10 Replacing the Cut-Off Thermostat
This thermostat cuts out power to the autoclave, in the event that all other
safety means do not function.
For example: If the safety thermostat is defective and the temperature
continues to rise, then the cut-off thermostat cuts out the power to the
autoclave. In order to restart the operation press the Reset Button. If the
autoclave is operated according to the instructions, and the thermostat
again cuts out, the Cut-Off Thermostat must be replaced.
Caution
Before starting, disconnect the instrument from the power source and
ensure that there is no pressure in the autoclave.
Allow the autoclave to cool before removing outer covers.
The Cut-Off Thermostat is located on the upper side of the fuse and
socket panel on the rear of the autoclave.
1. Remove the rear cover.
2. Loosen the heating band.
3. Unscrew the thermostat and replace it with a new one.
